Knowing is knowing, not knowing is not knowing." A generation of scholar Confucius was a person who carefully handled the relationship between "known" and "unknown". However, how should the relationship between "known" and "unknown" be clarified , but Confucius, who "recited but not made", seems to have never seriously solved it. As for how to obtain the "unknown" from the "known"? In the instruction of "The Analects", there is a very good insight: "It must also be rectified!" - Let's give the "unknown" a name first! Limited by the symbol system of the Book of Changes, people in Confucianism never seem to assign a symbol to "unknown" when making predictions.
Therefore, "unknown" has never had a definite position in the study of changes, and "algebra" cannot develop. . The title of "Father of Algebra" thus photo background removing fell to Diophantus, who named "Unknown". After the "unknown" was incorporated into the mathematical system, mathematical problems began to have a new syntax, and the emergence of equations also made "solving" an important goal in the development of algebra. shutterstock_525120643 Photo Credit: Shutterstock / Dazhi Images For example: the epitaph of "Diophantus"—— Passerby! Diophantus is buried here. 1/6 of his life was a happy childhood, 1/12 was a teenager, and after another 1/7 of his life, he got married. Five years after the marriage, he had a child, but the child lived to half his father's age and left.
After the child passed away, Diophantus spent another four years in deep sorrow, and finally ended his earthly life. (Can you guess how long Diophantus lived?) This is a typical algebra problem. Although as passersby, we don't know the age of Diophantus, but with the help of the unknown x, we can sort out the experiences of different periods in his life and easily calculate the age of Diophantus. age. Following the same rationale, we can try to discover more numerical laws in life, and sort out the “constant” between “variable numbers”. Mastering algebra obviously helps solvers get rid of the language barrier and find solutions to equations more easily. This is obviously a great tool for people who want to "rationally" deal with the "distri
